On November 6th 2013, Skype announced that the Skype API will be supported beyond December 2013 for recording apps like CallBurner – Skype’s official statement. This version uses the Skype API. You can ignore messages in the Skype client about CallBurner stopping working come December 2013.

Support for 5.1 and 7.1 sound systems (NOTE: Skype does not play surround sound, so recording is mono, but will now work correctly if you are using 5.1 or 7.1 – previous versions would not record correctly).
